Welterweight submission specialist T.J.
Waldburger has suffered an injury and will be unable to compete
as expected at UFC
161.

Replacing Walburger will be Kenny
Robertson, who now meets Sean Pierson at
the June 15 event. UFC 161 takes place at the MTS Centre in
Winnipeg and marks the promotion’s first trip to the Canadian
province of Manitoba. Headlined by an interim bantamweight title
showdown between reigning champion Renan Barao
and ex-WEC titlist Eddie
Wineland, the evening’s main draw airs live on pay-per-view and
will also see Mauricio Rua
and Antonio
Rogerio Nogueira clash in a light heavyweight rematch nearly
eight years in the making.

Robertson, 29, has split his last four fights after beginning his
career a perfect 10-0. The Illinois native debuted in the UFC in
2011 with a loss to Mike Pierce
but responded with a knockout of Lucio
Linhares outside the Octagon to close out the year. Most
recently, Robertson submitted Brock
Jardine with an innovative kneebar from back control, picking
up his first promotional win on Feb. 23 at UFC 157.
